Planetary Ball Mill Process in Aspect of Milling Energy
Planetary ball mill is a representative high-energy mill especially used for energy-intensive process like mechanical alloying, mechanical activation or mechanochemistry, etc. The term "high-energy" is often used to differentiate from "low-energy" conventional drum or ball mills. The name of planetary mill is derived from its unique kine- matics.

The composition of the milled powders was varied starting from a low value of 5 to about 50 at.% Zr. At a Zr content below 40 at.%, amorphization was achieved at a higher BPR of 30:1, i.e. more milling energy. The formation of an amorphous phase at Zr contents lower than 40% was achieved for the first time in this work and confirmed using TEM.
